Transistor Counting Systems for Scintillation Detectors

Scintillation detectors for x-rays

Recent research in the field of phosphor and scintillator materials and related detectors is reviewed. After a historical introduction the fundamental issues are explained regarding the interaction of x-ray radiation with a solid state. Crucial parameters and characteristics important for the performance of these materials in applications, including the employed measurement methods, are describ...

Cocktails for Liquid Scintillation Counting

It is most important to assure 4 π−geometry in liquid scintillation counting for accurate results1. Usually this can be assured by dissolution of the sample in an appropriate cocktail. The cocktail does not only contain a solvent but also at least one scintillator and surfactants for aqueous samples because aqueous samples are completely insoluble in the pure organic solvents and scintillators....

Nanoscintillation Systems for Aqueous-Based Liquid Scintillation Counting

Liquid Scintillation Counting

discussed, and he points out that merely because a disease is found to be familial in incidence does not mean it is hereditarily transmitted; leprosy, for instance, was long held to be a hereditary disease, and a law was actually proposed in the Norwegian Parliament forbidding the marriage of lepers for that reason. It was only with the discovery of the leprosy bacillus by Hansen that the true ...

New approach for calibration of pixelated scintillation detectors of intraoperative gamma cameras

Introduction:SURGEOSIGHT is a dedicated intra-operative hand-held gamma camera designed and manufactured by our team to be used for lymphoscintigraphy. Although conventional gamma cameras are widely used, they lack the capability of the sentinel lymph node (SLN) imaging in the operation room. Like conventional gamma cameras it is necessary to calibrate SURGEOSIGHT for linearity...
